A double free condition can corrupt the heap allocator\u2019s internal metadata, enabling attackers to manipulate memory layout and potentially achieve arbitrary code execution (RCE) under favorable conditions. In this case, the flaw is triggered during an early stream reset in HTTP/2, meaning it can be exercised pre-authentication by a remote client without requiring complex application-level interaction. Given that Apache HTTP Server is widely deployed in internet-facing environments, even a low-probability RCE path significantly elevates risk.\n\n\n\nAdditionally, the vulnerability exists in a core protocol module rather than an optional edge feature, increasing the likelihood of exposure. It is also important to note that this vulnerability specifically affects Apache HTTP Server version 2.4.66 only, and our mod_http2 packages are not affected as they are built against non-vulnerable httpd versions.",
